Background: Esophagojejunostomy is facilitated by use of a circular stapler, particularly when performed laparoscopically. The minimum patient size that will allow use of circular staplers in the small intestine is unknown. Materials and Methods: Retrospective review of esophagogastric dissociations performed at a single tertiary care institution for 48 months. This was combined with a geometric derivation of a size-estimation formula. Results: From the 7 cases identified, patients weighing >16 kg easily accommodated the 21 mm stapler. There was a narrow fit in the patient weighing 13.6 kg, and the 6 kg patient was too small for the stapler. Conclusions: Through a combination of clinical observation and physical reasoning, circular stapler applicability in small intestine is predicted by patient weight or intestinal measurement. Patients weighing >16 kg will accept the stapler, whereas patients <13 kg are likely too small. Alternately, on the basis of a geometric derivation, if the width of the flat intestine is >1.6 × the device diameter, the device will fit. This calculation can be applied broadly (e.g., incision length for laparoscopic ports or single-port access devices).
